CVE-2023-53716

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the skb tstamp tx() function within the networking subsystem. A previous fix for zerocopy socket buffer (skb) leaks introduced a new leak when skb orphan frags rx() fails, causing the cloned skb to not be freed before the function returns. This issue was identified using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc. The commit 50749f2dd685 attempted to address previous memory leaks related to zerocopy skbs and TX timestamps.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
